In only its second week on Hot R&B/Hip-Hop Songs, Drake's "Started from the Bottom" shoots 19-3 to become the rapper's 30th top 10 hit on the list. Only two other artists have posted 30 or more top 10s since the chart incorporated Nielsen data on Dec. 5, 1992: Lil Wayne with 34 and R. Kelly with 32.

Additionally, since Drake first cracked the top tier on the chart with "Best I Ever Had" on June 6, 2009, Lil Wayne trails him with only 19 top 10s in the timeframe. According to Nielsen SoundScan, "Started" sold 168,000 downloads last week, a 185% increase over the previous week's sales of 59,000.

Lil Wayne's "Love Me," featuring Drake and Future, stays put at No. 6 on the list while Rihanna's "Diamonds" continues its descent, falling 5-7 in its 21st week. Her "Pour It Up," however, remains stationary at No. 8 despite a 3-1 skip on R&B/Hip-Hop Airplay to claim her second chart-topper in 30 chart appearances and sliding 2-1 on Mainstream R&B/Hip-Hop for her sixth No. 1 there (viewable on billboard.biz).

Miguel's "Adorn" reclaims the No. 9 spot on the chart thanks to activity generated from his Grammy performance of the song. "Adorn" sold 65,000 downloads last week -- up 47% -- according to Nielsen SoundScan, marking the California singer's best sales week yet. On streaming services, "Adorn" was played 1.6 million times last week, a 261% increase over the previous week.

On Top R&B/Hip-Hop Albums, Rihanna's "Unapologetic" gets a Grammy gain as it moves 2-1 with a 71% increase to 41,000 copies. It is only the album's second week atop the list following its debut there on the chart dated Dec. 8, 2012.

A$AP Rocky's "Long.Live.A$AP" rises 4-2 with a 21% increase to 24,000 copies in its fifth week on the list while Alicia Keys' "Girl on Fire" jumps 7-3 with a 41% to just fewer than 24,000 copies.

Macklemore & Ryan Lewis' "The Heist" is displaced by Keys' jump and falls 3-4 with an 8% decline to 21,000 copies. Kendrick Lamar's "good kid, m.A.A.d city" rounds out the top five with a 6-5 rise, despite a 7% decrease to 18,000 copies.
